great job on the double pumper! how much would you say you invested in building that? far less then 550 bucks i assume? also are you using a hobbs switch to activate the second pump or is it always on?

 

i would say it was no more than 250 for the double pump. yes it is activated by a Hobbs switch 6 psi.

very cool turbo...not one we see too often here. Setup looks great. OT but are u actually a drill at benning? Went to bct at 1st/38th inf D co....over 8 years ago though. memorable place, benning is...no other installation quite like it. Follow me

 

Is the turbo ball bearing or journal bearing I did not see if this was answered anywhere.

 

ball bearing

 

Thanks, I really am considering this turbo for my 2g dsm but in journal bearing with .63 ar. From the looks of your graph the ball bearing starts to spool up hard at about 3600 rpm even with your 272 cams. I am going to keep my stock cams to see what the powerband feels like and hopefully I can expect to be spooling hard by about about 3750 from what PTE told me when I called.

 

A lot of that will depend on your setup as well. A friend of mine got 570hp out of this turbo on E-85, but that was at 42psi and every bolt on known to man.

I was considering doing something like this.

Current Mods:
Mods: Bolt-on
1g BOV, Perrin MBC, K&N drop in filter, custom 3" exhaust, Megan downpipe, Prothane motor mounts. walbro 255
Mods: Engine Management
dsmlink v3 lite (speed density parts in hand not installed yet), Defi boost gauge, AEM AFR gauge

Planned Mods:
PTE 5857 turbo journal bearing internal gate
ETS FMIC
Custom Southbend SS-X single plate clutch
FIC 1350cc bluemax injectors
ARP Headstuds
I plan on getting tuned by RRE using dsmlink v3 lite speed density

 

keep in mind im still a novice when it comes to tuning. so someone with a lot more experience and know-how could probably make it spool sooner.

i do enjoy this turbo very much.

i should have new numbers on speed density and FF manifold in the upcoming weeks.

 

Why would you use a journal bearing turbo when they offer the DBB option? especially when you are concerned with spool.

 

I wasn't trying to talk sh*t about your build by no means man. Sorry if you took it that way.

You are also still stock head and block, and from what we can tell that 570whp from my buddies build is the highest hp 5857 out there.

That little turbo forward facing on a stroker would be a blast dude!

 

I want journal bearing because its so much cheaper and according to PTE the journal bearing should only spool around 200-300 rpm slower than the dbb. I can get a 5857 journal bearing for 810 shipped compared to the 1350 - 1400 price for the ball bearing. I am not extremely concerned with spool and I use my Camaro as my drag car I want this just to be a fun street car.

 

i didnt take your comments offensively.

i just didnt want you to think that's the best it will spool.

i do plan on going with either 2.1L, 2.3L, or 2.4L in the summer time.

 

just a fyi but i would stay away from the journal bearing billet turbos. they are known to fail. Us and about 6-7 other friends we have that own/run shops were talking about it recently and all of us have been seeing them fail.

i would really like to see this sucker on a 2.3. i think it would be fun as hell on the street with a stroker. since the turbos dont actually gain any power past say 7k or so it would have a helluva powerband in a stroked car
